So I have a 2010 g37x coupe I'm lowered on elibach springs about a 2" drop I want to go 20x10+25 And 255/35/20 tires would that work or would the front rub?

 

You've also been posting about 11" rims, which ones are you considering?
The 10" +25 is a much easier fit than the 11s w/ the same offset, you'll be real close w/ the 10" +25, here's a 9.5 +30 running 265s and as you can see the fit is real flush, the 10" +25 would be another 11mm further out on teh rim and the 255 would bring it in a bit but not much, say an overall 8mm further out from Lt8ches' coupe

The 11" rims you're asking would be another 12mm out from the 10" so about 20mm further out from Lt8ches.
